AI Disclaimer: Cala does not permit the use of AI during interviews and technical testing so that we can properly assess thought process and skillset.

Responsibilities

• End-to-end design execution: Own visual design and user experience flows across web and mobile (iOS/Android) - from flows and wireframes through high-fidelity UI, interaction, and motion design - meeting accessibility standards (e.g., WCAG) throughout.
• Data visualization & clinical insights: Design flows, dashboards, and data displays that turn complex data into actionable insights.
• Design language & system: Create Cala's visual and interaction design language and the system behind it - component library, design tokens, versioning - so it scales across form factors and accessibility modes and maps directly to front-end implementation.
• User research & validation: With Product Management, conduct Voice of Customer (VOC) research, interviews, and usability testing for early-stage discovery and post-design acceptance testing.
• Multimodal UI: Partner with product and engineering to turn concepts into high-fidelity design documents, including notification and feedback moments across connected devices.
• Design documentation & handoff: Author and maintain UI/UX documentation, redlines, and specifications with rigorous version control for handoff to engineering.
• Design leadership & scaling: Lead cross-functional design reviews from concept through implementation, and scale design operations to support Cala's growth in a regulated medical device environment.

Skills and Experience

• Bachelor's degree in Graphic Design, Human-Computer Interaction (HCI), Interaction Design, related disciplines, or equivalent practical experience.
• 3+ years of digital UI/UX or product design experience with shipped web and mobile products, including healthcare platforms for patients and/or clinicians within HIPAA regulations and data privacy/Protected Health Information (PHI) constraints.
• Deep understanding of native mobile design standards, including Apple Human Interface Guidelines (HIG) and Google Material Design.
• Deep knowledge of accessibility standards (e.g., WCAG) and inclusive design, and direct experience developing accessibility-driven user interfaces.
• Familiarity with medical device usability engineering standards (IEC 62366, FDA Human Factors guidance) and comfort with the documentation and version-control rigor a regulated environment requires.
• Experience in Agile/Scrum environments, partnering closely with Product, Engineering, and QA.
• A portfolio showing strong visual design sensibility and end-to-end UX work across connected platforms.
• Proficiency in Figma, including components, auto layout, variables and modes, Dev Mode, prototypes, and design documentation practices.
• Hands-on with AI-assisted design tooling for concept exploration, research synthesis, and prototyping, with sound judgment about its limits in a regulated context.
• Proficiency in usability testing to validate design decisions.
• Experience creating and scaling a design language or design system, including design tokens, plus enough front-end literacy (HTML/CSS, React or SwiftUI) to collaborate on feasibility.

Nice to Have

• Wearable/Embedded UI: Experience designing for wearable or embedded device displays.
• Regulatory Usability Testing: Experience participating in Formative and Summative Usability Testing specifically for FDA submissions or CE marking.
• AI/ML-Enabled Products: Experience designing AI/ML-enabled or adaptive software in FDA-regulated products.
• Prototyping in Code: Comfort building interactive prototypes in code or with AI prototyping tools before handoff.
